Using it's concept, it is found that there is a 
probability that the first card is a club and the second one is black.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem:
- In a deck, there are 52 cards, of which 13 are clubs, hence
.
- Then, of the remaining 51 cards, 26 are black, hence
.
Then:
probability that the first card is a club and the second one is black.

Answer:
You start at -9
-Open circle
-shade towards the right (where all the positive numbers are)
Open circle - ones that don't have a greater than or equal to. If it does then it's a closed one.
Shade towards the right cause y is less than 9
The first thing we need to distinguish is what 1 and 3/4 means. So, 3/4 = .75, so 1 and 3/4 = 1.75
So, we need 1.75 cups of flour for one batch, since you're making three batches, you need three times as much, so
1.75 * 3
5.25 is the answer, to put it back in to fractions,
5 and 1/4 cups of flour are needed.
Answer:
Step-by-step explanation:
A) Using the foil method and distribution, you should get x²+10x+7x+70 from (X×X)+(X×10)+(X×7)+(7×10). When you combine these like terms, you get x²+17x+70.
B) Using the same ideology from part A, when you multiply x-3 into x-9. you should get x²-9x-3x+27. Simplifying this will give you x²-12x+27.
Answer:
The spinner has 6 equal-sized slices, so each slice has a 1/6 probability of showing up.
I guess that we want to find the expected value in one spin:
number 1: wins $1
number 2: wins $3
number 3: wins $5
number 4: wins $7
number 5: losses $8
number 6: loses $8
The expected value can be calculated as:
Ev = ∑xₙpₙ
where xₙ is the event and pₙ is the probability.
We know that the probability for all the events is 1/6, so we have:
Ev = ($1 + $3 + $5 + $7 - $8 - $8)*(1/6) = $0
So the expected value of this game is $0, wich implies that is a fair game.
